What might be wide court passage (7)
I believe the answer is:
extract
'passage' is the definition.
(extract is a kind of passage)
'what might be wide court' is the wordplay.
'what might be wide' becomes 'extra' (a cricket extra might be wide).
'court' becomes 'ct'.
'extra'+'ct'='EXTRACT'
(Other definitions for extract that I've seen before include "Short excerpt" , "Draw out - distillation" , "(Piece) remove(d)" , "Pull out as with tooth (7)" , "short passage from a book" .)
